Disaster strikes in a New York tunnel as explosions collapse both ends of it; a combustion ensues.

Josie acts like Madam Curie to explain how she discovered radiation and how it works. Beakman talks about how the fission of atoms produces heat, which makes radioactive materials glow. Beakman sets up a demonstration with mousetraps and ping pong balls (atoms) where he hits one and it causes a chain reaction of all of the mouse traps triggering.

After building a nest for the egg, the CyberSquad builds a leaf canopy to protect the nest from the rain. They try weaving a roof with the same pattern as that of the nest, but it doesn't work, as it lets rain through. They find a tree with a leaf pattern that slides all water off to the side and replicate the pattern to create their canopy.

Beakman challenge where he wraps a paper towel around the end of a paper towel tube and then fills the tube halfway with salt. Then pushes a plunger handle into the salt to try to break the tissue but he can't do it. He explains that this is because the push of the handle expels the air that the salt crystals come together to absorb all of the force and none is left for the tissue.

Beakman and Liza explain how static electricity works. They use plenty of real-world examples and humorous graphics in their explanation. They include atoms and electrons in their explanation.
